摘要:

利用有限元软件ABAQUS对钢筋混凝土框架结构构件中混凝土应变率进行了分析,将梁、柱的弹塑性在应力-应变层次上进行模拟; 研究了多维地震输入下应变率效应对钢筋混凝土框架结构弹塑性地震反应的影响以及同一地震波不同峰值加速度下钢筋混凝土弹塑性地震反应的应变率相关性,对比分析了考虑应变率与未考虑应变率下的弹塑性地震反应的差别。研究结果表明:框架柱的应变率明显大于框架梁,并且上部构件的应变率小于下部构件,构件跨中截面的应变率小于端部截面; 考虑应变率效应时结构的位移反应、基底剪力和弯矩发生改变,峰值加速度较大的地震波作用下应变率效应更为显著,应变率效应对钢筋混凝土框架结构弹塑性地震反应存在一定的影响,尤其对强震下结构进行抗震分析时应适当予以考虑。

Abstract:

The strain rates of concrete in reinforced concrete frame structure members were analyzed by using finite element software ABAQUS. The beam and column element nonlinearity was modeled in stress-strain relation level. Elastic-plastic seismic responses of reinforced concrete frame structure with strain rate effect under multi-directional excitation were studied. The seismic responses with strain rate effects were analyzed under same seismic wave and different peak accelerations. The results with strain rate were compared with those without strain rate to study the difference in the elastic-plastic seismic response. The study results show that the strain rates in beam elements are smaller than those in the column elements. The strain rate in the element is smaller on upside, and it is also smaller in the section of the mid-span. The displacement response, base shear and moment of structure were changed when the strain rate effects are taken into account. The strain rate effect under the stronger seismic wave is more prominent. The elastic-plastic seismic response of reinforced concrete frame structure is affected by the strain rate. The strain rate effects should be considered properly in the seismic analysis under intense ground motion.
